<h2><a name="rmic">Rmic</a></h2>
<h3>Description</h3>
<p>Runs the rmic compiler for a certain class.</p>
<p>Rmic can be run on a single class (as specified with the classname
attribute) or a number of classes at once (all classes below base that
are neither _Stub nor _Skel classes).  If you want to rmic a single
class and this class is a class nested into another class, you have to
specify the classname in the form <code>Outer$$Inner</code> instead of
<code>Outer.Inner</code>.</p>
<p>It is possible to refine the set of files that are being rmiced. This can be
done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i> and <i>defaultexcludes</i>
attributes. With the <i>includes</i> or <i>includesfile</i> attribute you specify the files you want to
have included by using patterns. The <i>exclude</i> or <i>excludesfile</i> attribute is used to specify
the files you want to have excluded. This is also done with patterns. And
finally with the <i>defaultexcludes</i> attribute, you can specify whether you
want to use default exclusions or not. See the section on <a
href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the
inclusion/exclusion of files works, and how to write patterns.</p>
<p>This task forms an implicit <a href="../Types/fileset.html">FileSet</a> and
supports most attributes of <code>&lt;fileset&gt;</code>
(<code>dir</code> becomes <code>base</code>) as well as the nested
<code>&lt;include&gt;</code>, <code>&lt;exclude&gt;</code> and
<code>&lt;patternset&gt;</code> elements.</p>
<p>It is possible to use different compilers. This can be selected
with the &quot;build.rmic&quot; property, the <code>compiler</code>
attribute. or a nested element.
<a name="compilervalues">Here are the choices</a>:</p>
<ul>
  <li>default -the default compiler (kaffe, sun or forking) for the platform.
  <li>sun (the standard compiler of the JDK &lt; JDK 9)</li>
  <li>kaffe (the standard compiler of <a href="http://www.kaffe.org" target="_top">Kaffe</a>)</li>
  <li>weblogic</li>
  <li>forking - the sun compiler forked into a separate process (since
    Apache Ant 1.7). Starting with Ant 1.9.8 this is the default when
    running on JDK 9+.</li>
  <li>xnew - the sun compiler forked into a separate process,
      with the -Xnew option (since Ant 1.7).
    This is the most reliable way to use -Xnew.
    <br></br>JDK9 has removed support for -Xnew and starting with Ant
    1.9.8 this option will be rejected by ant when running on JDK9.</li>
    <li> "" (empty string). This has the same behaviour as not setting the compiler attribute.
    First the value of <tt>build.rmic</tt> is used if defined, and if not, the default
    for the platform is chosen. If build.rmic is set to this, you get the default.

</ul>

<p>The <a href="http://dione.zcu.cz/~toman40/miniRMI/">miniRMI</a>
project contains a compiler implementation for this task as well,
please consult miniRMI's documentation to learn how to use it.</p>

<h4>CORBA support</h4>

<p>Java 11 removes the CORBA and JavaEE packages and rmic no longer
  supports either <code>iiop</code> nor <code>idl</code>. Starting
  with Ant 1.9.11 the rmic task will fail when using either while
  running Java11+ unless you fork the task and explicitly specify an
  executable.</p>

<p><a name="footnote-1">*1</a>:
<ul>
  <li>Maintaining compatibility, <code>base</code>, when specified by
    itself, serves as both the parent directory for any source files
    AND the output directory.</li>
  <li><code>destdir</code> can be used to specify the output
    directory, allowing for <code>base</code> to be used as the parent
    directory for any source files.</li>
  <li>At least one of either <code>base</code> or <code>destdir</code>
    must be specified and exist, or a runtime error will
    occur.</li>
</ul>

<h3>Parameters specified as nested elements</h3>
<h4>classpath and extdirs</h4>
<p><code>Rmic</code>'s <i>classpath</i> and <i>extdirs</i> attributes are <a
href="../using.html#path">PATH like structure</a> and can also be set via a nested
<i>classpath</i> and <i>extdirs</i> elements.</p>

<h4>compilerarg</h4>

<p>You can specify additional command line arguments for the compiler
with nested <code>&lt;compilerarg&gt;</code> elements.  These elements
are specified like <a href="../using.html#arg">Command-line
Arguments</a> but have an additional attribute that can be used to
enable arguments only if a given compiler implementation will be
used.</p>

<h4>compilerclasspath <em>since Ant 1.8.0</em></h4>

<p>A <a href="../using.html#path">PATH like structure</a> holding the
  classpath to use when loading the compiler implementation if a
  custom class has been specified.  Doesn't have any effect when
  using one of the built-in compilers.</p>

<h4>Any nested element of a type that implements RmicAdapter
  <em>since Ant 1.8.0</em></h4>

<p>If a defined type implements the <code>RmicAdapter</code>
  interface a nested element of that type can be used as an
  alternative to the <code>compiler</code> attribute.</p>

<h3>Examples</h3>
<pre>  &lt;rmic classname=&quot;com.xyz.FooBar&quot; base=&quot;${build}/classes&quot;/&gt;</pre>
<p>runs the rmic compiler for the class <code>com.xyz.FooBar</code>. The
compiled files will be stored in the directory <code>${build}/classes</code>.</p>
<pre>  &lt;rmic base=&quot;${build}/classes&quot; includes=&quot;**/Remote*.class&quot;/&gt;</pre>
<p>runs the rmic compiler for all classes with <code>.class</code>
files below <code>${build}/classes</code> whose classname starts with
<i>Remote</i>. The compiled files will be stored in the directory
<code>${build}/classes</code>.</p>

<p>If you want to use a custom
  RmicAdapter <code>org.example.MyAdapter</code> you can either
  use the compiler attribute:</p>
<pre>
&lt;rmic classname=&quot;com.xyz.FooBar&quot;
      base=&quot;${build}/classes&quot;
      compiler="org.example.MyAdapter"/&gt;
</pre>
<p>or a define a type and nest this into the task like in:</p>
<pre>
&lt;componentdef classname="org.example.MyAdapter"
              name="myadapter"/&gt;
&lt;rmic classname=&quot;com.xyz.FooBar&quot;
      base=&quot;${build}/classes&quot;&gt;
  &lt;myadapter/&gt;
&lt;/rmic&gt;
</pre>
<p>in which case your compiler adapter can support attributes and
  nested elements of its own.</p>
